LSKFT Expands Residual Voltage Tester Solutions for Safety Compliance Testing

Shenzhen LSKFT Testing Instruments Co., Ltd. continues to enhance its residual voltage tester solutions for manufacturers, laboratories and certification service providers that require reliable electrical safety verification. The instrument is also commonly referred to as a remaining voltage tester, and is used to evaluate the residual electric energy that may remain after a product is disconnected from the power supply.

Residual voltage testing is an important part of electrical safety evaluation for household appliances, medical electrical equipment, power products and laboratory test samples. By measuring voltage decay and discharge behavior after power interruption, the system helps engineers verify whether exposed plug pins, circuits or accessible parts meet the required safety limits within the specified time.

Designed for practical laboratory operation

The LSKFT residual voltage tester is designed with a stable measurement circuit, clear test workflow and configurable test timing. According to different customer requirements, the system can support test configurations such as L-N, L-PE and N-PE measurement paths, helping users adapt the equipment to different standards, sample structures and internal laboratory procedures.

Key application value
